“Every day my Grandaddy stayed by her side in the hospital taking care of her, just as he’d done for every one of the 60 years they’d been married — right up until the night she passed,” Sims wrote in his story on the site. “I heard so many stories about the impact my Mimi had on people’s lives over the years…But I couldn’t help but think about my Grandaddy — the single kindest, most generous man I’ve ever known — having to wrestle with the Earthly loss of his sidekick of over six decades.”

Sims tweeted a picture of his grandparents on their wedding day.

Plz pray for my granddad, who lost his wife of 60+ years. Here they were in 1954 on their wedding day. What a legacy pic.twitter.com/H1kfOJeRqb
